If disconnection of the restraint is necessary, turn off the gas supply before

disconnecting. Reconnect the restraint prior to turning the gas supply on and returning

the griddle to its installation position.

Casters are only supplied on a griddle stand. If the griddle is moved for any reason the

griddle should be re-leveled (see LEVELING in this manual).

FLUE CONNECTIONS

Do not obstruct the flow of flue gases from the flue, located at the rear of the griddle. It is

recommended that flue gases be ventilated to the outside of the building through a

ventilation system installed by qualified personnel.

From the termination of the flue to the filters of the hood venting system, a minimum

clearance of 18” must be maintained.

Information on the construction and installation of ventilating hoods may be obtained from

the standard for “Vapor Removal from Cooking Equipment”, NFPA No. 96 (latest edition),

available from the National Fire Protection Association, Batterymarch Park, Quincy, MA

02269.

STANDS

The griddle has an optional stainless steel stand with locking casters.

GAS CONNECTIONS

Gas supply connections and any pipe joint compound must be

resistant to the action of propane gases.

Use a ¾” NPT gas supply line for the griddle inlet, located at the rear of the griddle. All

flexible and semi-rigid gas supply lines must comply with the applicable ANSI standard.

To ensure maximum operating efficiency this appliance must be connected with a gas

supply line of solid pipe or a commercial type Flexible Connector with the net inside

diameter (I.D.) as large as or larger than the gas pipe inlet on this appliance. Codes

require that a gas shutoff valve must be installed in the gas line upstream of the griddle.

Prior to lighting, check all joints in the gas supply line for leaks.

Use soap and water solution. Do not use an open flame.

After checking for leaks all lines receiving gas should be fully purged to remove air.

TESTING THE GAS SUPPLY SYSTEM

When the gas supply pressure exceeds ½ psig (3.45 kPa), the griddle and its individual

shutoff valve must be disconnected from the gas supply piping system.

When the gas supply pressure is ½ psig (3.45 kPa) or less, the griddle should be isolated

from the gas supply system by closing its individual manual shutoff valve.

- 7-

GAS PRESSURE REGULATION

The VCCG griddle is constructed with internal gas regulators on each burner valve. The

valves are pre set to 4” W.C. on natural gas uni ts or 10” W.C. on propane gas units. An

external gas regulator is not required as long as the gas pressure supplied to the unit is

not greater than ½ psig (3.45 kPa) or 14” W.C. The recommended supply pressure

(upstream of the griddle) should be 7-9” W.C. for natural gas and 11-12” W.C. for propane

gas.

At no time should the griddle be connected to supply pressure greater than ½

psig (3.45 kPa) or 14” W.C.

ELECTRICAL CONNECTIONS

Electrical and grounding connections must comply with the

applicable portions of the National Electrical Code and/or other local electrical

codes.

Disconnect the electrical power to the griddle and follow lockout /

tagout procedures.

Appliances equipped with a flexible electric supply cord are provided

with a three-prong grounding plug. It is imperative that this plug be connected into

a properly grounded three-prong receptacle. If the receptacle is not the proper

grounding type, contact an electrician. Do not remove the grounding prong from

this plug.

Power supply for electric ignition is 120 volts, 2 amp, 50/60 Hertz, 1 phase.

Do not connect the griddle to electrical supply until after gas connections are made.

OPERATION

The griddle and its parts are hot. Use care when operating, cleaning

or servicing the griddle.

BEFORE FIRST USE

Remove all packing material and protective plastic from the surfaces of the unit. Before

leaving the factory the griddle is coated with vegetable oil as a rust inhibitor. Remove this

film when the griddle plate is being cleaned prior to its first cooking use. Heat the griddle

to 200-300°F to loosen and melt the coating, then clean the surface by adding water or

a non-corrosive, grease dissolving commercial cleaner, following the manufacturer’s

directions. Scrape the oil residue from the plate with a griddle scraper. Rinse thoroughly

and wipe dry with a soft clean cloth. Clean all accessories.

- 8-

SEASONING THE GRIDDLE

Season the griddle to avoid possible surface corrosion before first use, and after every

cleaning. This will also help reduce the sticking of cooked food product. Heat griddle to a

low temperature (300-350°F) and apply a small amount of cooking oil –about one ounce

per square foot of surface. Use a soft lint-free cloth to spread the oil over the entire

griddle surface to create a thin film. Wipe off any excess oil with a cloth. Repeat the

procedure until the griddle has a slick, mirror-like finish.

CONTROLS

POWER SWITCH

The VCCG turns off and on by a single power switch. Pushing the power switch to the

ON position is all that is required to put the unit into production once the thermostats

have been set.

IGNITER CYCLE LIGHT

The igniter cycle light is a clear hole where the user can view the diagnostic LED on the ignition

module. In order to view the light, user must have a straight line of sight through the hole to be able to

see the green or red light.

The igniter cycle lights are located at the 8 o’clock position to each corresponding

thermostat knob. There is one pilot and one igniter cycle light for each burner (12” section

of griddle). Once the power switch has been pushed to the ON position, the igniters will

begin to ignite the pilots. The igniter cycle light will flash the color green while attempting

to ignite the pilot. Once the pilot is lit and recognized by the igniter safety, the light will

illuminate a steady green color. The pilot must be ignited (burning) and the igniter cycle

light must be emitting a steady green color before the griddle burner will be allowed to

ignite.

If the pilot fails to ignite after approximately 90 seconds, the igniter cycle light will

illuminate a flashing red color that indicates the pilot did not ignite. Pushing the power

switch to the OFF position and then back to the ON position will restart the pilot ignition

cycle and the pilots will attempt to ignite again.

THERMOSTAT KNOB

Each 12” section of the griddle is independently controlled by a solid state thermostat

control. The thermostats have an operating range of 150 to 550 degrees for standard

steel and chrome plate surfaces (150 to 450 degrees for Rapid Recovery™ composite

plate option). The thermostat knobs will need to be turned to a temperature setting for the

burners to ignite. Each 12” griddle section may be turned off independently by setting the

corresponding thermostat to the OFF position. You may also leave all thermostats set at

the desired settings and turn all sections off at once by pushing the power switch to the

OFF position.

THERMOSTAT CYCLE LIGHT

The thermostat cycle lights are located at the 12 o’clock position to each corresponding

thermostat knob. The light will illuminate when the surface cooking temperature drops

below the thermostat knob set point. The illumination of this light indicates that the burner

for that zone is lit.

STARTUP OF GRIDDLE

1. Set all thermostats to the desired temperature set points.

2. Push the power switch to the ON position. The red light behind the ON should

illuminate indicating that electrical power is being supplied to the unit.

3. If the thermostat cycle lights do not illuminate a steady red color within

approximately 90 seconds, push the power switch to OFF and back to ON again, this

will restart the pilot ignition cycle .This process may need to be repeated several times

on the initial installation of the griddle or if the griddle has been disconnected from the

gas supply.

4. Check that all thermostat cycle lights are illuminating a steady red color to verify that

all burners are lit and functioning properly.

- 10 -

SHUTDOWN OF GRIDDLE

Push the power switch to the OFF position, all lights should go off indicating that the

griddle is no longer heating.

EXTENDED SHUTDOWN OF GRIDDLE

1. Push the power switch to the OFF position

1. Shut the main gas supply valve to the OFF position.

2. Unplug the griddle electrical supply cord.

3. Apply a coat of vegetable oil over the griddle plate to inhibit rust.

USING THE GRIDDLE

To preheat, turn the burners on about 20 minutes before cooking.

A uniform and systematic approach to loading the griddle will produce the most consistent

product results.

The griddle plate is steel, but the surface is relatively soft and can be scored or dented by

careless use of a spatula or scraper. Be careful not to dent, scratch, or gouge the plate

surface. Do not try to knock off loose food that may be on the spatula by tapping the

corner or the edge of the spatula on the griddle surface. Use spatulas with rounded

edges. Do not use tempered steel utensils. Do not chop on the griddle cooking surface.

ZONE COOKING

This griddle features infrared box burners in 12” sections (U-shaped burners optional),

each controlled by independent thermostat controllers. Each 12” section is a separate

cooking zone, and allows for cooking a variety of products over a single griddle plate.

The chart is a suggested usage of zone cooking. When zone cooking, it is suggested that

you start with your lowest temperature setting at either side of the griddle, increasing the

zone temperature as you move up the zone line. Typically, the temperature differential

between the center of one cooking zone to the center of another zone that is directly

adjacent cannot be varied by more than 50 degrees. Some heat transfer from one area to

the next is to be expected. These zone cooking guidelines will vary depending on product

temperatures, size and shape. This guide should be adjusted to suit your product and

operational cooking preference.
